A blog (a contraction of the term weblog) is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Users of a blog may comment on "posts"
Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic.

In schools blogs are used to provide opportunities for authentic audience for students' writing as well as being a communication for sharing teaching and learning within the global community.
